Possible Causes
Weak compressor, Failed start relay/PTC, Undersized or failing overload protector, Low line voltage
How to Fix / Troubleshooting
Safety: Unplug the unit before touching compressor components. Components may be hot.
Steps:
- Check line voltage: Use a multimeter to verify that the outlet voltage is within the specified range (typically 110–125 VAC). Low voltage can cause hard starting.
- Inspect start relay and overload: Remove and test these components as described in the compressor not running scenario. Replace if defective.
- Allow cooling: If the compressor is very hot, allow it to cool for 30–60 minutes before retrying.
- Evaluate compressor: If new start components do not resolve the issue and voltage is correct, the compressor may be failing internally and require professional replacement.
Warning: Do not repeatedly force the compressor to start; this can cause further damage.
